T 0 (JM whom it may concern.

Be it known that I, CHARLES A. PENNY, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented new and useful Improvements in Lamps for Incubators, of which the following is a specification.

This invention comprehends the provision of an incubator attachment, in the nature of a lamp disposed to illuminate the interior of the incubator to enable the operator to see the thermometer, and to watch the progress of the. hatching without opening the door of the incubator which is not a good practice for various well known reasons.

An important object of the invention resides in the construction and arrangement of parts whereby the attachment can be readily associated with an incubator, and is designed for adjustment to accommodate itself to walls of different thicknesses.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a view in elevation of a portion of an incubator showing the attachment in position for use.

Figure 2 is an edge elevation.

Figure 3 is a sectional view taken on line 3--3 of Figure 1.

Figure 4 is a view somewhat similar to Figure 1 of a modified form of the invention.

Figure 5 is a sectional view taken on line 55 of Figure 4.

Referring to the drawings in detail and particularly Figures 1 to 3 inclusive, A indicates generally an incubator of any well known construction, the thermometer being indicated at B. In this form of the invention, I provide one end of the incubator with openings 10 to which the wires 11 and 12 respectively are passed from the electric lamp 13 to the battery 14 and switch 15. The combined electric light lamp socket and reflector is secured in any suitable manner to the inner side of the end wall of the incubator through which the wires are passed, the

lamp socket being indicated at 17 and the reflector at 18. The reflector may be of any suitable size and configuration, and disposed with respect to the electric light bulb 19 so as to deflect the rays of light downwardly so as to illuminate the thermometer B and also the egg chamber, so that the operator can watch the thermometer and the progress of the hatching without opening the door of the incubator. It is not a good practice to admit the cold air during hatching time which would result by opening the door of the incubator, nor is it a'good practice to hold a lamp, match, or other illuminating means in front of the incubator to enable the operator to see the thermometer, as it causes the chicks to rush toward the light or front of the incubator with the result that the weaker chicks are some times trampled upon and injured. The attachment can be conveniently and easily installed, while the switch may be of any suitable construction without departing from the spirit of the invention. i

In Figures 4 and 5 I have illustrated a modified form of the invention wherein the electric lamp socket is indicated at 20 and the reflector to which it is attached indicated at 21. The socket 20 is extended to provide a fixed tubular member 23 which is adapted to pass partly through the opening provided in the wall of the incubator, while telescopically fitted in the fixed tubular member 23 is a similar member 24 providing-at its outer end a switch at 25. By reason of this construction, the attachment may be adjusted in quick order to accommodate itself to incubator walls of different thicknesses. The battery is indicated at 26, and the conducting wires at 27 and 28. These wires in this form of the invention are passed through the tubular members 23 and 24.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to the details herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim is The combination with an incubator having an opening in one wall thereof, of an attachment therefor comprising a reflector including a relatively large portion, and a reduced tubular portion projecting from one end of the large portion, said reduced portion being received by the opening in said incubator Wall, to support the reflector thereon, an electric light bulb arranged'in the reflector, a tubular member telescopically fitted in said reduced tubular portionof the reflector and terminating to provide a flange Intestimony whereof I afliX mv signature. 15
